Analyte monitoring device and methods of use
First Claim
1. A glucose monitoring system comprising:
- a subcutaneous in vivo sensor for monitoring a glucose level of an interstitial fluid of a user;
a sensor control unit coupled to the sensor to output one or more signals associated with the monitored glucose level of the interstitial fluid of the user; and
a receiver/display unit in communication with the sensor control unit and comprising;
a receiver to receive the outputted one or more signals associated with the monitored glucose level of the interstitial fluid of the user from the sensor control unit;
an input device to receive an input from the user, wherein the input comprises, a medication sensitivity, drug delivery information, a food intake, and an exercise level;
a processor to evaluate the one or more signals received by the receiver to produce a first set of results comprising;
(i) the glucose level in interstitial fluid of the user,(ii) a rate of change of the glucose level, and(iii) an acceleration in the rate of change of the glucose level,wherein the processor further evaluates the input from the user and the first set of results to determine a dose of a medication; and
a display in communication with the processor.

Abstract
An analyte monitor includes a sensor, a sensor control unit, and a display unit. The sensor has, for example, a substrate, a recessed channel formed in the substrate, and conductive material disposed in the recessed channel to form a working electrode. The sensor control unit typically has a housing adapted for placement on skin and is adapted to receive a portion of an electrochemical sensor. The sensor control unit also includes two or more conductive contacts disposed on the housing and configured for coupling to two or more contact pads on the sensor. A transmitter is disposed in the housing and coupled to the plurality of conductive contacts for transmitting data obtained using the sensor. The display unit has a receiver for receiving data transmitted by the transmitter of the sensor control unit and a display coupled to the receiver for displaying an indication of a level of an analyte. The analyte monitor may also be part of a drug delivery system to alter the level of the analyte based on the data obtained using the sensor.
